"Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates. For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.
Exodus 20:8-11
A distinction that must be kept in mind is that between the particular enactments of any law and its sanctions. There are, for example, some enactments associated with the Ten Commandments that are no longer binding today. In Moses' day capital punishment was administered for some violations of the law, such as adultery. This is not done today; but it is the penalty that has changed, not the law itself, whose sanction remains unchanged. It is still wrong to commit adultery, nor is it any less heinous in God's sight now than it was then. In the same way, surely, although the extremely heavy penalties visited upon Israel for violation of the Sabbath are not exacted today, the sin is just as great, and the sanction at the heart of the commandment unchanged. In the same way, although it is true that believers do not live by the commandments, but in the Spirit (the reason why we do not steal being not that the commandment says we must not, but that as believers indwelt by the Spirit, we do not want to), the sanction of the commandments is still binding on us. It is still wrong to steal, to kill, or commit adultery. And since in every believer there is always also a dark, unbelieving side ('Lord I believe, help thou mine unbelief') he can never safely dispense with that sanction; it must ever be there to lead him, again and again, as a schoolmaster, to Christ. And the sanction of the fourth commandment was never needed so much as today, when even in the Church man's assertion of his independence of the will of God is so rampant and uninhibited.
